Method and system for assisting the piloting of an aircraft in landing phase

Abstract

A method and system for determining local information which is dependent on a local runway state when the aircraft is in movement on the runway in order to update, in real-time, or practically in real-time, data used by a braking assistance system, according to whether the local runway state associated with the determined local information indicates a runway deterioration relative to a reference runway state used initially.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application claims the benefit of the French patent application No. 1355499 filed on Jun. 13, 2013, the entire disclosures of which are incorporated herein by way of reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to a method and a system for assisting the piloting of an aircraft, and to an aircraft equipped with such a system.[0003]During the phases of take-off and landing, and more generally of movement on the ground of the aircraft, knowledge of the surface state of the runway is of capital importance.[0004]Indeed, prediction of braking performance of the aircraft depends on that knowledge. It is thus possible:[0005]to estimate as best possible the distance required to stop the aircraft at the time of its landing, in the interest of safety,[0006]not to overestimate that stopping distance required to immobilize the aircraft and thus not to excessively penalize the operations of use of the runway and of the...

AI Technical Summary

Benefits of technology

This patent is about an assistance system for piloting that uses real-time data to improve the braking performance and safety of an aircraft during landing. The system receives information about the condition of the runway from a previous landing or a ground station, and updates the braking data to make it more accurate and relevant for the current conditions. This way, the system can adjust the braking of the aircraft in response to any degradation in the runway state, ensuring a safer and more effective landing.

Problems solved by technology

However, the braking performance of an aircraft on a contaminated runway and thus the required stopping distance are difficult to predict on account of the difficulty of reliably and precisely knowing the runway state, which is decisive in the deceleration of the aircraft.

This runway state information, sent to the aircraft in approach phase, is however of low reliability and may become rapidly out of date.

To be precise, the runway state characteristics are highly volatile over time.

However, the runway state so determined and provided to the aircraft on approach phase does not enable such a possible runway degradation occurring between the two landings to be shown.
